FIELD: heating.
SUBSTANCE: invention relates to the field of fan-construction, in particular to fans used in devices for drying with use of hot gas. The technical result is achieved in that the high pressure fan of device for drying with use of hot gas, comprising an impeller wheel, a hub of the impeller wheel, mounted on a shaft of the electric motor with a horizontal axis of rotation, and the fan housing, with the input and output windows, additionally comprises a sealing ring, a gland packing in the hub of the impeller wheel and the holes in the impeller wheel.
EFFECT: invention is directed to increasing the lifetime of the electric motor when the fan is mounted in the device for drying, due to eliminating the ingress of hot gases in the casing of the electric motor, by reducing pressure behind the impeller wheel wall, in the area of its attachment to the electric motor shaft and insertion of a gland packing in the impeller wheel hub.
